• A new process for removal of Ni catalyst at the tip of carbon nanotubes vertically grown by the hot-filament chemical vapor deposition (HFCVD) has been suggested. First, vertically grown carbon nanotubes were oxidized in a furnace at 480℃ and then Ar ion bombardment was carried out in an ion mass doping system (TMDS). With these treatments, the catalyst particles located at the tip of vertically grown carbon nanotubes could be removed entirely. It is expected that the removal of the catalyst may improve the emission characteristics and the hydrogen storage capacity of the vertically grown carbon nanotubes significantly.
